The error bars are the Standard Error
of Measurement * 1.96, or a 95% confidence interval. The Flynn Effect Adjustment was done when culturally reduced rates were available. The calculation was done from 1980 to 1986 with the rates converted to 16 SD and subtracting the American full scale rate. Excessive trust should not be placed on the differences between the countries; the error bars often overlap with the averages of other countries. Some of the Flynn Effect rates are based on better data than others. And notice that it is unsatisfactory to subtract the American full scale rate instead of a culturally reduced or performance rate.

The following are some children’s relatively
modern IQ scores relative to American norms (IQ=100), on a 15 SD scale and
based on both verbal and performance type data, unless otherwise stated.
The Asian data are the highest scores found in the data sources. That is,
sometimes studies find lower Asian scores. On average, children
from Asian countries get about a 107 IQ relative to American norms.

2. Chinese children, in or around Beijing
scored 109.4. According to Li, Jin, Vandernberg, Zhu, and Tang, 1990, as
cited in R. Lynn (1997), Geographical variation in intelligence. In Helmuth
Nyborg (Ed.) The Scientific Study of Human Nature. I kept Lynn’s
adjustment for the Flynn Effect (The WISC-R Chinese standardization was
done 10 years later than the American).

3. In Nagoya Japan, the score was 110.24.
It was adjusted up by 3.34 points because testing was done on the Canadian
Cognitive Abilities Test (see note 1). Source: Takeuchi and Scott (1992)
as cited by R. Lynn (1997), Geographical variation in intelligence. In
Helmuth Nyborg (Ed.) The Scientific Study of Human Nature. It seems
that the Japanese gains have started to level off.

4. South Korean children got a score
of 109 versus British children. Source: Lynn and Ja Song (1994) as cited
by R. Lynn (1997), Geographical variation in intelligence. In Helmuth Nyborg
(Ed.) The Scientific Study of Human Nature.

5. Taiwanese children versus British
children: 104.7, on a culturally reduced test. Adjusted for the Flynn Effect
by R. Lynn (1997), Geographical variation in intelligence. In Helmuth Nyborg
(Ed.) The Scientific Study of Human Nature.
